Conor Kennedy, the son of Bobby Kennedy Jr., was rushed to an Aspen hospital suffering from a severe allergic reaction to nuts.

A source tells us, “Conor went into anaphylactic shock on Dec. 26 . . . Luckily he . . . was quickly back on the slopes.”

Other Kennedys there for the holidays were Max, Vicky and their kids, Bobby Jr. with Cheryl Hines and his kids, including Conor (the onetime love of Taylor Swift and now a Harvard student), Kyra, Aidan and Finn, Kerry Kennedy and daughters and Maria Shriver.
